SportsDayDFW.com special contributor Jon Machota answered reader questions during a live chat Tuesday. Here are some highlights:

How does the Dline look to you this year? Depth looks real shaky to me.

Jon Machota: Depth definitely isn't a strength on the defensive line. If that front four is going to be effective, Spencer, Ware, Ratliff and Hatcher need to be on the field often. If there is a significant injury, I think Tyrone Crawford has the most upside of any of the reserves. He could have a breakout season if he's called upon to play significant time.

What can you tell us about the new Special Teams coach, and what will be difference we see this year?

Jon Machota: From what I've seen during OTAs and mini camp, Rich Bisaccia seems like your typical energetic special teams coach. He's worked with Kiffin in Tampa and the two won a Super Bowl so that has to be a positive. The thing that has impressed me most about Bisaccia was how apologetic he was about leaving Auburn to take the Cowboys job. He seemed genuinely embarrassed about only being there for a couple weeks.

If the Boys all stay healthy don't you think they could win more like 14 games and the Super Bowl. There are so many awesome players now.

Jon Machota: I can't see the Cowboys winning 14 games even if everyone stays healthy, which won't happen. I think the max number of games they could win is 11. And as far as winning the Super Bowl, I think it's highly unlikely. But if the Cowboys reach the postseason and Romo performs like Flacco did during the playoffs last season I guess anything is possible.
